He did absolutely everything he could to be the best damn dam possible, even as his own mother pulled away. Unable to hide her disgust over the fact that Izuku refused to abort the baby.
Because of it all, Izuku has to do online school, and even gets a job.

Flash-forward, Katsuki is an extremely powerful Enigma, and people at UA flock to his side. Wanting to be in his atmosphere.
One day Katsuki brings the prettiest little Omega over, and they’re shocked. Was this a friend? A hookup?
“Yo extras, show respect to my dam.”

They’re over the moon! Oh that’s so cuuuute! Katsuki is a Mama’s boy! They are extremely kind and shower sweet adorable Mama Izuku with attention.
Then everyone is stunned when Katsuki kisses Izuku full on the lips. Not a sweet little chaste family kiss.

It’s deep and sensual, as Katsuki pulls him close and ruts against him. Without knowledging everyone’s shock, he tells them they’re going upstairs.
When Katsuki comes back later after dropping his mom back off at home, Kirishima braves the question.

“You…you said that was your mom?”
Katsuki goes to heat up the leftovers his dam had given him with a sweet kiss before he had to leave. “Yeah?”
He looked at the others who had been on Katsuki’s floor in their rooms when they 100% heard Katsuki and Izuku fucking.

“Um…like…kinky? Like Mommy play?” He chokes.
Katsuki frowns, irritated. “No, that’s my dam. I already said.”
They’re stunned speechless.

When they bring it up to their teacher, worrying that maybe Izuku is taking advantage of his son, the man sighs.
“Katsuki mated him.”
“What?!” They yell.
“I questioned him myself, and it’s a completely consensual and mutual bond.”

“Katsuki…is in love with his own dam?” Some of the Omegas that had been crushing on him are confused.
Many try to persuade Katsuki to their beds, but the Enigma never shows a hint of interest. They see Izuku a lot over the years.

While a lot of them are still sort of weirded out, confused, and don’t really know how to feel—Izuku is astonishingly sweet and kind. It’s impossible to not love him.
Katsuki also dots on his dam/mate and spoils him rotten. It’s obvious they’re so in love.

When Katsuki becomes a big hit on the hero seen, the HC pulls him aside and tells him he can’t be vocal about being mated to his dam. They won’t allow it. They present a really pretty young Omega, saying this is who he’ll be taking around to events and ‘dating’

She drapes herself all over Katsuki as they explain this. Batting her eyes and pushing out her lustful scent.
“Do you understand?” The president says, as all the board members nod along.
Katsuki stares at them, then grabs the Omega’s face gently.

They smile, happy he’s complying. Only to startle as the Omega starts screaming. They watch in horror as Katsuki stares emotionless into her eyes as he slowly crushes her head.
14
Terror fills them as they hear her gurgled whimpers of pain, scratching desperately at his arms before Katsuki is showered with gore as her skull finally gives in and her brains splatter.
He drops her without care. Staring at them. It’s silent for a long moment.

“RSVP my mate as my plus one at the hero awards next weekend.” He says, no commands before walking away.
They try a few threats to get Katsuki to comply, but the Enigma is utterly fearless. He doesn’t give a single fuck about what anyone thinks.

He shows off his dam, now covered in glittery massive jewels and wearing expensive designer clothes, at every single opportunity. Katsuki speaks of how loving his dam was and how hard Izuku worked to give Katsuki every opportunity possible.
17
He’s unashamed of being honest that Izuku is in fact the person who birthed him, his dam. He’s also completely shameless about Izuku being his beautiful mate, his Omega. How he’s planning on having pups with his mate, and building a big family.

The HC comes to the scary realization one day after an Armageddon level villain can only be put down by Katsuki.
He’s too fucking powerful. To ever lose as a hero, to tell what to do, or threaten.

Katsuki gets away with literal murder. If he ever encounters rapists while patrolling, he will annihilate them. If he encounters physically abusive partners or parents, he will beat them within an inch of their life.

People are simultaneously terrified shitless of DynaMight, yet feel safer than ever. Because if you’re not doing anything wrong, DynaMight is an awesome hero who cares about his fans.
Sex related crimes and abuse cases have plummeted astronomically.

People learn to see Katsuki’s relationship as cute and very romantic. Katsuki wanted the person who would love him most in the whole world!
The HC learns that Katsuki has everyone in the palm of his deadly hand, and they can do nothing about it.
